ARCH-SUPPORT ADJUSTER.

To all whom it may concern:

Be it known that 1, JAMES W. ARROW- snrrn, a citizen of the UnitedStates, residing at Morristown, in the county of Morris and State of NewJersey, have invented a new and useful Improvement in Arch- SupportAdjusters, of which the following is a specification.

The improvement relates to devices designed for the special purpose ofbending and adjusting metallic plates for supporting the instep arch ofthe human foot and the objects of the improvement, among others, are toprovide means whereby the adjustment of such plates to the contour ofthe foot arch may be quickly and accurately made without injuring themetal or the covering of non-metallic material usually applied to theplate; to provide a simple, compact and durable adjusting device soconstructed and arranged that the arch support may be placed therein'andoperated upon in various ways; and to thus dispense to a great extentwith the use of pliers or the like in accomplishing the adjustment.

The improvements consist in the combination, construction andarrangement of parts hereinafter described and claimed and illustratedin the accompanying drawings.

In the said drawings, Figure l is a plan of an arch support adjustingdevice embodying the improvements; Fig. 2 is a side elevation of thesame; Fig. 3 is an end view; Fig. 4 is a partial vertical longitudinalsection.

It should be understood that arch supports of the kind designed to beoperated upon by the device which is the subject of this application aredesigned for the relief and cure of the disease of the bones of thehuman foot commonly known as flatfoot, which disease manifests itself ina falling or flattening of the bony arch of the foot, comprising thecalcaneum or oscalcis, the astragalus, the cuneiform bones and themetatarsal phalanges, and that the treatment of all cases which haveadvanced beyond the incipient stages involves the adjustment of the archsupport to the depressed contour of the foot arch and then the gradualraising of the arch of the plate, and consequent raising of the footarch, longitudinally and transversely, when required, by adjustment ofthe plate from time to time as tolerance is established. It willtherefore be apparent that great accuracy and precision are oftenSpecification of Letters Patent.

required in the adjustment of the plate, and that this adjustment mustbe made at different parts from time to time, depending upon theposition of the bones comprising the arch of the foot which is beingtreated.

The base plate S is of wood or other suitable material and of greaterlength than breadth, and on either side of it near the middle thereofare mounted standards A of substantially U form inverted. Between theapices of these standards the cam lever B is mounted by means of thebosses G which have bearing recesses to receive the pintles D of the hubF. The bosses G have screw bolts I extending through them near thestandards A and passing down and entering the base S, and between thesebolts a block J is mounted by having the said bolts passed looselythrough vertical bores near its ends, so that it may move up and down ina vertical plane thereon. Helical springs H are strung on the bolts Ibetween the block J and the base and serve to raise the said block toits uppermost position after it has been depressed, and to hold it insuch position normally. M extending downward from its lower side, andthis boss is provided with a cover or cushion K of leather or othersuitable nonmetallic material.

The base S is provided with a longitudinal groove 0 for the purpose ofguiding the sliding plate N which has feet or tongues W at its endsprojecting into said groove. One of these plates is located at each endof the base and they are fixed in all positions to which they may bemoved by means of a bolt P extending through slots V therein andprovided with a thumb-nut R. Blocks T of substantially the same width asthe boss K on the block J are located at the inner ends of the slidingplates N, and are provided with covers or cushions U, and upon theseblocks the support is placed when it is to be adjusted, as shown bydotted lines in Figs. 2 and 4:. It will be seen that the blocks U may bemoved longitudinally to vary the distance between them or theirrespective positions with reference to the block J to any desiredextent, and this adjustment not only accommodates the device to archsupports of different sizes but permits the plate of the said support tobe bent on any desired are and at any part.

The cam C is so formed that when the lever B is oscillated between itsposition in The block J has a boss Fig. 2 and its position in Fig. itforces the block J down or permits it to rise under the action of thesprings H, and it is through this ram that pressure is applied to theplate of the support to etl ert the desired adjustment. The uppersur'tace oi the block J is curved to atl m'd a proper contact surfacetor the. cam. and the recess of each boss G which receives the pin l) isopen at the lH)tTt'()1ll**"2lS shown where the top of the standard A iscut away in Fig. Q so that the cam lever may be removed and used a, amallet tor the purpose of bending the extreme outer edges of the plate,or conveniently placed for paclviing and shipping.

What I claim is 1. In a device of the character described thecombination of a cam lever, suitable supports upon which said lever ismounted, comprising standards having recesses in their upper parts andopenings leading from the said rcccs, at an angle thereto andprojections on said lever adapted to engage said reces es, a verticallyreciprocating block, a yrinp; for iolding said block nor mally in itsupper position, the construction and arrangement ot the lever and blockbe ing such that the block is caused to descend by a movement of thelever, a plurality of sliding blocks located below the normal po sitionof the first-named block and outside the plane of its reciprocation, andmeans for moving the said blocks.

2. In a device of the character described the combination of a camlever, suitable supports upon, which said lever is mounted, comprisingstandturds having recesses in their upper parts and openingsleadingitrom the said recesses at an ai'i rle thereto and projections onsaid lever adapted to engage said recesses, a vertically reciprocatingblock, a spring for holding said block normally in its upner position,the construction and arrangementof the lever and block being such thatthe block is caused to descend by a movement ot the lover, a pluralityof slidingblocks located below the normal position ot the first-namedblock and outside the plane of its rcciproraition, means for moving thesaid blocks comprising plates on which saidbloclqs are mounted, a base,a slot in the said base, and projections on the said plates engagingsaid slot.
